Objective To elucidate the effects of endothelin-1(ET-1) on expression of extra-regulated kinase 1(ERK 1), cell cycle and changes of Ca 2+ in activated hepatic stellate cells (HSCs). Methods Effects of different concentra tions of ET-1 on ERK 1 expression were determined by Western blotting. Effects of ET- 1 on cell cycle were observed by flow cytometry(FCM) analysis. Effects of ET-1 on changes of calcium concentration and cell area were observed by laser scanning confocal microscopy (LSCM). Results ET-1 could inhibit the expression of ERK 1 i n a dose-dependent manner, compared with the control, the expression of ERK 1 in E T-1 highest concentration group decreased 10.91%?3.36% (P

BACKGROUND: Changes of leukocytes are related with some postoperative complications after renal transplantation. OBJECTIVE: To observe dynamically the level of white blood cell (WBC) and its morphological changes using automatic blood cell analyzer to evaluate its relationship with infection, immunosuppressive intoxation and acute rejection. DESIGN, TIME AND SETTING: Observation and controlled trial was performed at Second Xiangya Hospital, Central South University from June 2004 to October 2005. PARTICIPANTS: Sixty-eight patients who received renal transplantation were selected. According to clinical symptoms and laboratory biochemical indexes, X-ray, B ultrasound, and renal puncture biopsy, the patients were divided into stable group (n=36), infection group (n=9), intoxation group (n=6) and acute rejection group (n=13). METHODS: The blood routine was tested with Sysmex XE-2100 automatic blood analyzer following renal transplantation and WBC manual differentiation was done to observe peripheral blood morphology, their liver function. In addition, renal and liver functions were detected by automatic biochemical system 7600A. MAIN OUTCOME MEASURES: WBC count and its morphological changes in peripheral blood and liver and renal function after renal transplantation. RESULTS: WBC count of the stable group and intoxation group was normal, and that of the acute rejection group and infection group were significantly higher than the stable group (P

Objective To observe the effect of externally-applied Honghua liquid and catus on phlebitis induced by amiodaone.Methods One hundred and two patients with phlebitis induced by injection of amiodaone for the treatment of arrhythmia were randomly divided into control group(n=50)and treatment group(n=52)from January 2012 to December 2013. Patients in the control group were independently treated only by 50 % Honghua liquid, while the patients in the observation group were treated by hot dressing with Honghua liquid followed by wet dressing of catus. The curative effects in both groups were observed and compared.Result The total effective rate in the treatment group was significantly higher than that in the control group(χ2=6.275, P<0.05).Conclusion Hot dressing with Honghua liquid combined with wet dressing with catus is a simple and effective method to treat the phlebitis induced by injection of amiodaone.

Objective: To explore the role of calcium/calmodulin-dependent protein kinase-II δ (CaMK-II δ) in doxorubicin (DOX) induced cardio-toxicity in experimental rats.
Methods:①The rat’s cardiomyocytes were treated by DOX and the cell proliferation, protein expression and activity of CaMK-II δ were examined.②CaMK-II δ gene was knocked out by CRISPR method, the changes of DOX induced cell apoptosis and NF-κb activity and miR-146a expression were detected.
Results: DOX could inhibit cardiomyocyte proliferation, the protein expression level of CaMK-II δ was similar and the activity was increased. CRISPR method may effectively knock out CaMK-II δ gene. Compared with normal cells, the cells from CaMK-II δ knocked out rats had decreased sensitivity to DOX induction, suppressed NF-κb activation and miR-146a up-regulation.
Conclusion: CaMK-II δ participated in DOX induced cardio-toxicity in experimental rats and NF-κb and miR-146a were involved in this process.

OBJECTIVE To investigate the relationship of resistance and ?-lactamases of Acinetobacter baumannii.METHODS The bacteria cultured were identified with API 20NE system.The susceptibilities of the bacteria were detected by disk diffusion method.The ?-lactamases produced by these strains were characterized by three-dimensional test and 2-mercaptopropionic acid inhibition assays.RESULTS In 150 strains,the resistant rates of strains were 4.0% to cefoperazone/sulbactam.The resistant rates to imipenem,meropenem,piperacillin/tazobactam,ampicillin/sulbactam and levofloxacin were between 20.0% and 55.0%.The resistant rates to ceftazidime,cefepime,aztreonam and amikacin were above 60.0%.Three-dimensional test showed that 37 strains(24.7%) produced extended spectrum ?-lactamases(ESBLs),66 strains(44.0%)produced AmpC enzymes and 16 strains(10.7%)produced carbapenemases,in which 12 strains(8.0%) produced metallo-?-lactamases.CONCLUSIONS The resistant rates of A.baumannii to routine antibiotics are high except cefoperazone/sulbactam and carbapenem.It is the most important reason for multi-drug resistance that the strains of A.baumannii produce ESBLs,AmpC enzymes and metallo-?-lactamases.
